Civitai

Civitai is the largest open community for Stable Diffusion, SDXL, Flux, and video AI models — hosting over a million model checkpoints, LoRAs, embeddings, and VAEs uploaded and rated by creators. Beyond hosting, Civitai operates a hosted AI image, video, audio, and language generation service through its Orchestration API, which races workflows across providers (Flux 1/2, SDXL, SD1, Z-Image, Qwen, Seedream, Grok, WAN 2.1-2.7, Kling, LTX2, Vidu, Veo 3, HunyuanVideo) and supports LoRA training jobs. The Site API exposes the public catalog plus user vault, permissions, and AIR identifier resolution. OAuth 2.0 with PKCE and per-app Buzz spend caps lets third parties build delegated experiences without owning a user's full credit balance. Generation is metered in Buzz, a virtual credit topped up via memberships or one-off packs.

Civitai publishes 11 APIs on the APIs.io network, including Blobs API, Creators API, Enums API, and 8 more. Tagged areas include AI, Artificial Intelligence, Image Generation, Video Generation, and Stable Diffusion.

The Civitai catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Civitai’s developer surface includes authentication, developer portal, documentation, getting-started guide, signup flow, support, engineering blog, and 44 more developer resources.
